IMPROVEM ENT lN HARVESTERS.

Specification forming part of Letters Patent No. 18,267, dated September 22, 1857.

To all whom it may concern:

Be it known that I, SAMUEL PENOCK, of Kennett Square, in the county ot' Chester and State of Pennsylvania, have invented a new and useful Improvement in Grain and Gra-ss Harvesters; and I do hereby declare that the following is afull, clear, and exact description ot' the same, reference being had to the annexed drawings, making a part ot' this specification, in which- Figure lis a plan or top View of a harvester with myimprovement applied to it. Fig. 2 is a back or end view ofthe main frame of the same.

Similar letters ot' reference indicate corresponding parts in the two gures.

rIhis invention relates to an improved arrangement of the crank-shaft which drives the sickle, in connection with the device by which it is thrown in and out of gear with the driving-wheel.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the main frame of a harvester.

B is the driving-wheel fitted therein. Gis the y linger-bar attached to the main frame, and D is the sickle, which works on the nger-bar. rlhese parts are constructed in the usual way, and therefore do not require a minute description.

E is the crank-shaft, the bearings a a ot1 which are attached to a frame, F, which is se cured on the main frame A. IThis frame is formed ot' a bar, b, having two arms, c d, projecting at right angles from it, one from each end. (See Fig. l.) The frame is secured to the main frame by a pivot, e, which passes through the outer end ot' the arm c. The outer end of the opposite arm, d, works underneath a auge, f, at the lower part of an upright, 7c, and a guide-pin, g, passes through a slot, h, in the bar b. rEhe bearings a d ofthe crank-shaft E are placed one at each end of the bar b.

To one end of the shaft E a crank-pulley, t', is attached, and G is a connecting-rod,one end of which is attached to the pulley' t, and at the opposite end is attached to the sickle D.

0n the shaft E, and near the end opposite to that to which the crank-pulley@l is attached, there is placed a bevel-pinion, j, which, when the frame F is properly adjusted, gears into a cogged rim, H, on the driving-wheel B.

I is a small shaft placed in the upper part ot' uprights la k on the frame A. rlhis shaft has an eccentric, l, on its end, and also a crank, m. A strap, u, is tted on the eccentric l, and one end of a rod, 0, is attached to said strap, the opposite end ot' said rod being attached to the bearing a of the shaft E. A pin,p,is attached to the crank, which pin, as the crank is turned, will bear or strike against either side of' one of the uprights 7c.

From the above description otparts it will be seen that the pinion)l may be thrown in and out ot gear with the rim H on the driving-wheel B by moving the frame F, the frame being moved by tur-ning the crank 'm of the shaft I, the length ot' the movement of the crank being governed by the pin p. By this arrangement the crank-shaft E and its bearings a a are moved bodily toward and from the drivingwheel, and the crank-shaft is not liable to be strained and bent, as would be the case it' shifted in and out of gear with 'the drivingwheel in the usual way.

By my improvement the crank-shaft may be fitted snugly in its bearings, no unnecessary play being` allowed nor required, and the driving-gear is consequently not liable to get out of repair nor wear unevenly, but is kept in perfect and true running order until it is entirely worn out.

It will also be observed that by means ot' the regulating-pin p all danger of throwing the gear in too far is obviated, while by the peculiar construction and arrangement of the parts the shiftingv is easy, besides being in such a position as to be easily and quickly operated from the drivers seat W.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent', is

Adjusting and regulating the position of the crank-shaft E by means of mechanism constructed, arranged, and operating in the manner set forth. f
